I bought several of these. I did have one that didn't have any torque and had to return it, but for the most part these are great

Great stepper for the RoBo 3D I built a clone and these motors work great with the RAMPS and default drivers. The wires are plenty long enough, and although I would have loved a connector at the motor itself, I can always add one myself. No issues with drift or double-stepping. Plenty strong enough for all 5 motors of my machine.

Like all OSM steppers, this is an awesome little motor. I'm using it for a direct-drive MK8 Bowden extruder on a large Kossel delta. Running this motor at 1-amp makes it only slightly warm and provides plenty of torque to push over 120mm/sec ABS print speeds at .3mm layer height...that's extruding a LOT of plastic. I'm very happy with this motor and will continue to use them for all my extruders.

Nothing I can complain about. I just wished I purchased something more powerful for my application. I beat up this motor, held it still while trying step, and turning it while it was trying to hold, but no complaints per the motor. I got it stupid hot in an attempt to really work it, and it still responds quite well. So I only have good recommendations for this motor. (I'm going to order the 84oz motors for my application, and use the same seller :D )

I bought this stepper motor as a replacement on my 3D printer. I needed the shorter motor for clearance purposes. So far, the motor is running smooth with no re-calibration needed. The previous motor was loud with a lot of vibration. This one is much more quite with no vibrations detected. So far, so good!

Stepper works great, I'm using it on my FT 2020 i3 for the Y axis. The stock motor had a droning sound whenever the bed moved long distances at high speed. This one quieted it up a bunch. The stock motor was rated 4.8kg/cm but this one seems to have plenty of power to do the job.

This motor is a beast. Using it on my Wanhao DI3. With a Flexion HT extruder. With the torque that this motor provides, i am able to tighten the jam nut much tighter than what i would before. Print quality and torque are very noticeable. Had to adjust stepper driver for 1.44v. The motor is a beast.

Purchased Six of these motors, they work great. Using them on my 3d printer. Only gripe I have is I wished that the wires were removable from the motor side as a plug. But for the price it worth getting. They run smooth have not had any problems with them so far.

I bought this motor is replace the weak extruder motor on my Wanhao Duplicator i3 v2 that I recently changed to a RAMPS 1.4 board. I've been using it all weekend, and so far everything is working out pretty good. I haven't gotten around to reinstalling my Flexion extruder kit back on after changing back to the stock block with the all-metal upgrades, but this thing can definitely power that. Not that noisy (although nothing is that noisy when sitting next to the fans that came on the Wanhao), and haven't had any clogs or skipped steps yet. I know the stock motor is 34mm, but a 6mm difference is negligible for me, and the tradeoff in torque gain was worth it. One note though, I had to remove some metal from the heatsink to make it fit, since the shaft is a bit longer than stock as well. Also, be sure to adjust your voltage, because the stock motors run at a pretty significantly lower voltage than these.

I ordered two of these to replace my Z motors on a RepRapGuru I3 machine. Only one motor was bad, but figured it would be best to replace as a matched pair and pull the good one aside for a standby replacement for any other failures. They were a bolt-up, drop in replacement for the stock motors. Though, this item has a higher amperage rating and slightly higher torque, so I can under-drive them a little an lose nothing in the trade.
